The article presents the main advantages of using coiled tubing technologies during wells workover. The problem of low durability of the sealing element of the wellhead sealant is touched caused by considerable frictional forces. The relationship between complications arising during launching and lifting works (LLW) and the low durability of the sealing elements of the sealant is shown. The necessity of materials development providing lower coefficients of friction during sealing elements operation is substantiated. The results of the research of wear-out resistance and physical-mechanical properties of EP SKU PT-74-brandpolyurethane filled with solid lubricationpowders are submitted, the abrasion patterns of the obtained polyurethanes are given, the type and amount of the filler providing the less wear-out of the sealing element are determined. The tests conducted with the help of MI-2 abrasion machineresulted in measuring of friction coefficients abrasion of polyurethane samples with solid lubricants various fillings. The regression analysis revealed the properties of the material that mostly affects the sealing element wear-out. The regression equation is built.

The article considers the hydrodynamics of formation fluid discharge from a formation prospective interval opened by drilling by means of a jet pump installed in the inner cavity of the drill-pipe casing string in the wellbore near-bottom hole section. The solution of the hydrodynamic problem of the stabilized process of bottom-hole fluid discharge connecting the dynamics of the injected, recovered and ascending flows of the circulating system is given. Based on the accepted design scheme of the jet pump and its placement in the internal cavity of the near bottom-hole part of the drill-pipe casing string, protected by patents, the general solution of the stationary hydrodynamic problem connecting the dynamics of the injected, recovered and ascending flows of circulating liquid through its pressure in the mixing chamber of the jet pump is made. The obtained analytical solutions are presented graphically and allow to estimate the value of the flow-rate of the extracted bottom hole fluid through the flow-rate of the injected liquid at the wellhead.

The article presents the description of a geophysical method, namely, seismic survey to predict complications during wells drilling.Complications that appear in the wells drilled in the region during the previous years are analyzed. The time spent on their shutdown is discussed as well. Analysis of seismic profiling data to find the reasons for complications such as washing fluid acquisitions is also proposed because their liquidation requires 80 % of time and money.

Specific features of a deposit’s geo-mechanical structure, identified by means of the analysis, were accounted for during wells designing. It allowed three-times cost reduction on wells drilling in the new site of a field as compared with the wells predicted with the help of traditional methods application.

 

Keywords: seismic survey; complication of wells; absorption zones isolation; fracturing of rocks.

The article presents brief analytical generalizations on the quality and efficiency of wells cementing, factors that violate the technology of casing strings cementing as well as on the related problems. On the example of the cement bond log, the thermodynamic specific features of the production columns cementation are considered. It is shown that the problem of wells poor-quality cementing is associated with the irreversible processes of destruction of the grouting mortar-stone initial properties, which are typical for traditional (unsystematic) technologies.

Alternatively, the «Multi-technology complex of the wellbore hydromechanical hardening» is proposed, its advantages over traditional methods are noted. The complex excludes complications occurrence in various geological and technical conditions when constructing oil and gas wells, such as: gas, oil and watershowings, absorption of up to 50 m3/h intensity, instability and hydraulic fracturing of rocks, blowouts and emissions. While during wells operation, the complex provides the prevention of inter-layer flows and annulus fluid manifestations, a two-times and more decrease of the product water-flooding, a non-linear increase in the well production rate and the oil recovery factor.

The article presents the laboratory studies results on the choice of the increased-density process fluid composition to be used for wells killing during capital and current repairs at fields and underground gas storage facilities. The use of a process liquid without a solid phase for wells killing under anomalously high reservoir pressures (AHRP) makes it possible to obtain an economic effect in the oil and gas production industry by maintaining productive horizons characteristics and the low cost of the proposed composition.

The offshore oil and gas producing facilities operate in difficult climatic conditions and are exposed to various environmental effects. One of such effects are sea currents. Besides the direct load on the submerged parts there exist additional effects such as the occurrence of the vortex trial behind the submerged elements, causing a force effect, that can bring their subsequent breakdown. The alternation of the occurrence and the breakdown of these vortices leads to vibrations, which in case of resonance with their own frequencies of oscillations of the offshore facilities elements can lead to the occurrence of vibration stresses. The article suggests a method of determining the frequency of vortex formation and determines the flow rates which start and finish resonance phenomena on the example of the offshore platform column.

 

Keywords: offshore oil and gas structures; hydrodynamic forces; formation and breakdown of vortices; frequency of vortices failure.

The article presents «Dodicor V 4712» corrosion inhibitor, developed by «Clariant» firm (Germany), that was subjected to a laboratory pilot testing in the formation waters, mostly saturated by H2S,of wells: Nos. 75, 115, 63, 43, 112, 117 and 38 of S. Balgimbaev field of «Zhaikmunai» Oil and Gas Production Department. It should be noted that the passport of the inhibitor under study lacks ecological and toxicological data. Based on the data of the reagent’s chemical components, obtained during the laboratory pilot testing, it was concluded that «Dodicor V 4712» inhibitor, despite its good corrosion-resistant properties, doesn’t answer the practical purposes due to its high toxicity.

One of the most important problems when operating gas multi-layer fields and underground gas storages (UGS) is hydrocarbons inter-layer migration through faults and stratigraphic unconformities from one natural reservoir to another one, causing serious consequences (formation of man-caused deposits, appearance of inter-layer and inter-column manifestations, etc.). To solve many practical problems associated with the design and regulation of field development and UGS operation as well as with setting of individual wells operation modes, it is necessary to study the objects dynamic processes aimed at determining of the parameters characterizing the hydrodynamic properties of wells and formations (hydraulic gas conductivity, piezo-conductivity of a formation, a well productivity, etc.).

The authors propose an effective method to study the dynamic processes of gas environment of multi-layer fields and UGS, based on the introduction of an indicator in a gas carrier into the formation through the injection well, sampling from the production well and determining the change in the indicator concentration over time in the products of a production well. During the period of maximum gas pressure, the central injection wells located in one or more operational horizons are selected based on the location pattern of producing wells along the area. At the same time, the indicators of different colors are pumped into different central injection wells, thus allowing to quantitatively determine from what central injection well the indicator migrated and to obtain a more adequate volumetric picture of migration processes both within the gas-saturated part of the deposit or UGS in one horizon and between different horizons.

 

Keywords: multi-layer reservoir; research; gas environment; indicator; reservoir characteristics; layer; microgranules; observation well; injection well; flow rate; sampling.
