Analytical and field researches on determination of the relationship of the zenith angle’s intensity changes with the lateral force on a bit, with mechanical drilling rate and other factors affecting a hole deviation are carried out. The real data on the intensity of the five wells deviation in Nong Jogansky field, drilled by the oriented BHA, with the calculated values of the lateral forces, available on the bit, with account of the real deviation of the holes by the zenith angle and the azimuth are compared. A linear dependence, at any moment of time, between the intensity of the increase, decrease of the zenith angle and the lateral force on a drill bit is revealed. Introduced The concepts of maximum (minimum) possible values of the intensity of deviation and lateral force, dimensionless intensities and forces are introduced. To predict the intensity of the deviation there received reliable regressive dependence of this value on the drilling mechanical rate, quantitatively valid for Nong-Jogansky field. As a result of the conducted researches there appeared the possibility of BHA required characteristics identification to predict the necessary intensity of zenith angle increase or decrease in specified drilling conditions, thus contributing to the quality increase of directional wells projected profiles implementation.

 

Keywords: BHA; deviator’s angle of bend; borehole; intensity of deviation; lateral force on a bit; rate of penetration; dimensionless dependence; prediction of a hole deviation.

There is provided to deal with function of depth from the length of the well along with standart profile, which is the dependence of the deviation of the borehole axis from depth in vertical direction. This dependence allows to determine depth and length of any point on the axis of the well as in the design calculations, as in calculations at the stage of well construction. Analytical and approximate graphical methods of depth from length dependence for inclined and horizontal wells are elaborated. Analytical dependence of depth from current length for each interval of the well is derived. Algorithm of analytical dependence use is mentioned. The accuracy assesment of determining the parameters for each method is given. It is noticed, that trajectory of essentially horizontal wells, designed on the actual surveying measurements, is possible to approximate by polynomial dependence of depth from the length location of the points on the axis.

 

Keywords: well path calculation; well planning; inclined and horizontal wells; flowing pressure; combination pressure chart.

The updating of the methods, developed to predict and liquidate drilling and cementing fluids absorption in the rocks with opened fractures and abnormally low formation pressures, is still one of the most urgent problem when drilling wells in the Urals-Volga and the Eastern Siberian regions.

The method for calculation of the isolation process of the simplest model of the drilling fluids absorption zone, represented by the ideal vertical fracture, is developed in this article. The method application is illustrated by the test numerical example. The radius of spreading and the volume of viscous-plastic grout that provide a fracture isolation are calculated. Based on the Volarovich-Gutkin universal equation for viscous-plastic liquid flow, the chronogram of the well-head pressure during isolation is built.

 

Keywords: absorption; fracture; grout; viscous-plastic liquid.

Currently, no one t needs to explain how important is the fire safety of industrial objects at all stages of its existence. This problem becomes even more urgent when constructing oil and gas fields in view of the indispensable presence of some diesel fuel stock at the tank farm required for transformer substations operation and special fire hazard of the mined from the bowels of the product extracted out of sub-soil assets. The construction is carried out in remote uninhabited areas with poor transport network, with no professional forces and means near-by to extinguish fires. This fact makes it vitally important to provide drilling sites with the adequate amount of equipment for fire extinguishment and the necessary water supply.

The method of the required water supply calculation, recommended by the set of rules «Oil and Petroleum Products Tank Farms. Fire Safety Requirements» is developed based on the design of vertical steel tanks and is not suitable for the case of fuels-lubricants storage in horizontal tanks. Calculations carried out without accounting for the tanks constructions underestimate the required amount of water that can dramatically affect the facilities and equipment state of a drilling site in case of fire and lead to construction workers deaths.

Based on the calculations performed, the authors of the article prove the fact that in case of equal volumes and identical arrangement of tanks in a set, horizontal tanks cooling requires much more water than vertical tanks. According to the authors concept, the formula for determining the required water consumption to cool the horizontal tanks should account for not the perimeter length of the burning tank and half the length of the adjacent tank perimeter, as is the case for vertical tanks, but the length of the burning tank contour in plan and half the length of this contour for the reservoir adjacent to the burning one.

The adjustment of the methodology for determining the estimated supply of water, required for firefighting, will provide a drilling site with a sufficient water supply, thus ensuring the possibility to localize the fire with minimal losses saving builders lives and property.

 

Keywords: field; fuel storage; firefighting; water reserve calculation; horizontal tanks.

An urgent problem when designing offshore oil-gas structures is a progressive collapse calculation. It is not enough to calculate the loads of the constructed object that will affect it during its operational period. It is required to make a series of calculations forced by the unforeseen situations, which can cause irreversible aftereffects. The article presents recommendations in case of a progressive collapse occurrence and considers the design scheme of the support block of the ice-resistant stationary platform with account for the collapse of the bearing structural elements.

 

Keywords: construction; ice-resistant stationary platform pipeline system; progressive collapse; «LIRA SAÐR» PC.

The article describes the development and field introduction of a well killing technique that is different from traditional method of wells killing. The essence of the technique lies in the fact that before conducting geological-technical measures or when replacing the submerged pump, a well killing with the excessive pressure in its mouth or gas manifestation is made by the killing liquid, compounded by its composition with the formation fluid, through the lift pipes of the well excluding a filtration into the productive formation.

Due to helium high penetrability, provision of threaded connections leak-tightness of drill-pipe casing strings in the planned helium storages wells is an urgent problem both at wells design and construction stages.

The results of laboratory testing of some factors influence on threaded connections leak-tightness, given in the article, allow to narrow the choice of a threaded connection type out of the set of the threaded connections produced by the domestic industry for further use when constructing wells of helium concentrate underground storage.

PJSC «Gazprom» Standard 2-3.2-174-2007, being in force at present, provides the output control of the thermal-physical properties of the thermally insulated lift pipes (TLP) at the stage of factory testing and the control of the thermal insulation characteristics of the TLP by evaluating the thermal insulation characteristics of a well support at the final stage of its construction. However, the quality of the TLP at the most important stage, prior its lowering into the well, remains uncertain, that is, there is no technology of input control of the thermal insulation characteristics of TLP after their storage and (or) transportation to the work site. Also, there is no control over the thermal-physical properties of TLP when they are reused, for example, after wells workover.

The proposed express-method is designed to conduct operational input control of thermal insulation characteristics of TLP in the field conditions prior to their lowering into the well with the purpose of rejecting off-specification samples.
