| titleOfInvention | Fluid bridging plug of high pressure resistant controlled degradation chemistry forming and its production and use |
| abstract | The invention discloses fluid bridging plug of a kind of high pressure resistant controlled degradation chemistry forming and its production and use, this fluid bridging plug is at normal temperatures, sodium acrylate, acrylamide, dimethyl diallyl ammonium chloride, N ' N-methylene-bisacrylamide, azo-initiator, vegetable jelly, poly(lactic acid), hydrochloride and silicon-dioxide are added to the water and stir, then before said mixture adds pit shaft, add organic borate cross-linker and ammonium persulphate capsule wherein, stir obtained.This fluid bridging plug high-temperature-resistant high-pressure-resistant is good, and can degrade under field conditions (factors).When utilizing it to carry out multistage fracturing, first by bottom pressure break, under enter oil pipe, inject described fluid bridging plug liquid, above carry liquid level place on oil pipe to fluid bridging plug, pressure break last layer after the solidification of fluid bridging plug, realize multistage subsection fracturing of separate layers and so forth, and can not work the mischief to pit shaft. |
