Abstract
The invention relates to a high molecular polymer water absorbing material for well drilling leak stoppage. The water absorbing material is obtained by copolymerizing a monomer A, a monomer B, a crosslinking agent, an initiator and an inorganic filling material at a certain constant temperature. The water absorbing material has the advantages of simple preparation process, easiness and convenience for operating, 3-7 times of water absorbing multiple, high toughness, high deformation capability and capability of resisting high temperature of 150 DEG C in drilling fluid, and is suitable for high-strength leak stoppage, pressure-bearing leak stoppage and reservoir shielding temporary stoppage operation of pores, cracks and crushable leak formations in a drilling process.
Description
Technical field:
The present invention relates to a kind of drilling leakage blockage and use the high molecular polymer water-absorbing material, belong to macromolecule material preparation area, particularly relate to a kind of drilling plugging agent.
Background technology:
Leakage is the medium-term and long-term technical barrier that exists and fail fine solution of drilling process.The processing of leakage has at present been leaked by seeing of beginning and has just stifledly been developed into present putting prevention first, anti-blocking bonded technical thought, but along with the going deep into of exploratory development, the complicated Slot Handling of bad ground remains a leak stopping difficult problem.With the high molecular polymer is material of main part; Cooperate first, final set linking agent; Crosslinking time regulator and toughener etc.; Artificial control patching materials gets into drop ply with liquid state or colloidal form, and formation pore and fracture morphology and size flexibility are good with missing, and becomes one of direction of patching materials and leakage stopping technology development gradually.
High molecular polymer class patching materials generally is prepared from through hydrophilic high molecular materials such as vinylformic acid, acrylic amides, in order to improve plugging agent gelling strength and toughness, also in becoming the glue process, adds inorganic materials, like CN1080642A; Or the adding inorganic filling material forms better intensity and flexible water-absorbing material such as CN85102156 in the polymkeric substance building-up process.The aforesaid propylene acids is owing to added activation kaolin and wilkinite; Make the composite performance of water-absorbing resin increase, especially resistance toheat increases, generally below 120 ℃; Be not suitable for 150 ℃ of high-temperature stratum leak stopping demands; And the water-absorbing material that forms suction multiple is too high, and toughness is relatively poor, causes leak stopping slurry preparation difficulty, plugged zone bearing capacity low.
Summary of the invention:
The objective of the invention is for a little less than overcoming above patching materials bearing resistance, deficiency such as temperature resistance ability, develop a kind of drilling leakage blockage with high molecular polymer class water-absorbing material.
