Description
Technical field:
The present invention relates to the Multi-layer oil well sand control simulation test device that a kind of oil extraction in oil field engineering test is used.
Background technology:
In order to improve sand control effect, abroad each major company and university have set up many covers sand control simulation test device.But be mainly the research of carrying out for SIMULATION STUDY OF GRAVEL PACKING IN HORIZONTAL WELL sand control, function singleness.If your university of the companies such as U.S.'s Schlumberger, Haliburton, Chevron, Bake Hughes and Britain Hei Ruite-watt is since the beginning of the eighties, utilize Large Real size SIMULATION STUDY OF GRAVEL PACKING IN HORIZONTAL WELL simulation test device, carry out the research of SIMULATION STUDY OF GRAVEL PACKING IN HORIZONTAL WELL mechanism test, and set up SIMULATION STUDY OF GRAVEL PACKING IN HORIZONTAL WELL Mathematical Modeling, carry out SIMULATION STUDY OF GRAVEL PACKING IN HORIZONTAL WELL numerical simulation, parameter preferably with the researchs such as sand controlling result prediction, obtained desirable achievement.Domestic Oil Mined Technology Research Inst., Shengli Oil Field has set up a set of physical analog test apparatus that is suitable for SIMULATION STUDY OF GRAVEL PACKING IN HORIZONTAL WELL.But for Multi-layer oil well sand control simulation test device, but have no report both at home and abroad.The present invention is a set of Multi-layer oil well sand control simulation test device.The experimental rig of inventing needs to produce the present situation with sand control in a plurality of oil reservoirs simultaneously for oil well, can be in designed model, by dismounting model body, filling effect simulation while carrying out oil well individual layer and multilayer sand control, sand controlling result simulation, pit shaft deposition Simulations, explore the impact of various factors (pressure, flow etc.) on each layer of sand controlling result, optimize back-up sand construction parameter, evaluate the sand control ability of different model resin sand, thereby construct favourable foundation is provided for on-the-spot sand control design and sand control.
Summary of the invention:
The object of this invention is to provide a kind of Multi-layer oil well sand control simulation test device, this device has solved in prior art and has tested function singleness, lacks the problem of Multi-layer oil well sand control simulation test device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Multi-layer oil well sand control simulation test device, is comprised of bolt, packing ring, flat cover, insulation layer, sealing ring, heating collar, vertical cylindrical shell, sand base support, horizontal cylinder, sand control screens, supporting plate, right flat cover, support; Flat cover all adds packing ring with bolt with horizontal cylinder and is connected with vertical cylindrical shell, vertical cylindrical shell, at vertical and horizontal cylinder two ends, be respectively equipped with sealing ring, vertical cylindrical shell, horizontal cylinder are all made with circular stainless steel hollow section, at cylindrical shell, be equipped with the semicircle heating collar made from heating panel outward, heating collar is equipped with the semicircle insulation layer of making by alumina silicate heat-preservation cotton outward; Base support is welding with vertical cylindrical shell, support and horizontal cylinder; Vertical cylindrical shell upper end and horizontal cylinder right-hand member are equipped with flat cover and the right flat cover in sealing ring and T-shaped liquid inlet and outlet hole; At vertical cylindrical shell lower end flat cover, with bolt, add after packing ring, heap sand in cylindrical shell, then flat cover is built in vertical cylindrical shell upper end with bolt, add packing ring and fix; In horizontal cylinder, sand control screens is installed after heap sand and supporting plate is built right flat cover by its right-hand member, bolt is fixed with adding packing ring.This simulation test device can simulation well under 1～3 layer of oil well carry out the work progress of machinery and chemical sand control, and the sand control construction manufacturing process of oil well afterwards.
While simulating the work progress of multiple zone oil machinery and chemical sand control, by feed tube, quartz sand or resin sand are injected in multiple zone simulation cylindrical shell under certain temperature and pressure situation, concurrently injected mulling liquid is through cement sheath, enter into concrete dynamic modulus stratum filtration simulation layer, then fixed, unnecessary liquid is discharged pit shaft through drain pipe.Liquid in simulation layer, after high-temperature process, resin sand is cemented in nearly pit shaft area, plays the effect of sand control.While simulating the manufacturing process of multiple zone oil machinery and chemical sand control, from drain pipe, oppositely to concrete dynamic modulus stratum filtration simulation layer, simulation wellbore hole, inject similar liquid or mulling liquid, the sand situation that contains of observing produced liquid in oil well from the feed liquor mouth of pipe, realizes the manufacturing process after multiple zone sand control.This device is for normal temperature to 95 ℃, pressure≤30MPa.
Wherein model cylindrical shell can be changed, and can adjust according to the different borehole size of oil well.When feed tube is simulated sand control construction and pilot production for multiple zone oil well, injection and the outflow of mulling liquid used, drain pipe flows out or injects from multiple zone well simulation test device for mulling liquid or similar liquid etc.In simulation concrete dynamic modulus stratum filtration simulation layer, can fill dissimilar reservoir sand, according to present situations such as the degree of porosity of the different oil reservoirs of oil well, permeability, formation cementations, carry out lab simulation filling.Cement sheath, for simulating the cement sheath of actual multiple zone oil well, adopts certain thickness steel plate to replace the thickness of cement sheath under real well.The pressure sensor differential pressure sensor of some is installed by different parts in concrete dynamic modulus stratum filtration simulation layer, at drain pipe place setting pressure adjuster, can be controlled the pressure condition of different oil reservoirs, different parts.Its test result can be detected accordingly, transmit and be processed by pressure detecting system, transfer of data and treatment system.To meet the demand of multiple zone sand control simulated test.
The modes such as during enforcement, whole Multi-layer oil well sand control simulation test device is taked to be threaded, welding realize
The invention has the beneficial effects as follows: this experimental rig has novel structure, use easy to operate feature.This device can effectively instruct different layers position to carry out machinery and chemical sand control working design and on-the-spot sand control simultaneously and construct, and for the screening of sand prevention material, load fluid formula, the optimization of sand control construction parameter provides foundation.
