Embodiment 1

[0022] Embodiment 1: The lost circulation agent of inert material while drilling, the raw material comprises 50 parts to 80 parts of rigid material of 100 orders to 150 orders and 30 parts to 70 parts of mineral fibers of 100 orders to 120 orders in parts by weight. The drilling inert material plugging agent is obtained as follows: the required amount of 100 mesh to 150 mesh rigid material and 100 mesh to 120 mesh mineral fiber are mixed uniformly to obtain the drilling inert material plugging agent.

Embodiment 2

[0023] Embodiment 2: the plugging agent of inert material while drilling, the raw material includes 50 parts or 80 parts of rigid material from 100 mesh to 150 mesh and 30 parts or 70 parts of mineral fiber from 100 mesh to 120 mesh in parts by weight. The drilling inert material plugging agent is obtained as follows: the required amount of 100 mesh to 150 mesh rigid material and 100 mesh to 120 mesh mineral fiber are mixed uniformly to obtain the drilling inert material plugging agent.

Embodiment 3

[0024] Embodiment 3: The plugging agent with inert material while drilling, the raw material includes 50 parts of rigid material from 100 mesh to 150 mesh and 70 parts of mineral fiber from 100 mesh to 120 mesh in parts by weight, the inert material plugging while drilling The agent is obtained by the following method: the required amount of 100-150-mesh rigid material and 100-120-mesh mineral fiber are uniformly mixed to obtain the inert material lost circulation agent while drilling.

Abstract

The invention relates to the technical field of oil field leaking stoppage agents, and relates to a while-drilling inertia material leaking stoppage agent, as well asapreparation method and a use method thereof. The while-drilling inertia material leaking stoppage agent comprises the following raw materials in parts by weight: 50 to 80 parts of a rigid materialof 100 to 150 meshes, and 30 to 70 parts of mineral fiber of 100 to 120 meshes. The leaking stoppage performance of the partially acid-soluble rigid material leaking stoppage agent is more excellent than that of acommon leaking stoppage agent commercially available in China, and the leaking stoppage performance of the partially acid-soluble rigid material leaking stoppage agent is equivalent to that of aforeign leaking stoppage agent. The raw materials of the partially acid-soluble rigid material leaking stoppage agent are wide in source and low in price, so that the production cost of the partially acid-soluble rigid material leaking stoppage agent is less than that of the foreign leaking stoppage agent, the cost performance of the partially acid-soluble rigid material leaking stoppage agent is more excellent than that of the foreign leaking stoppage agent, and technical support is provided for improving the complicated treatment efficiency of well leakage.

Description

technical field [0001] The invention relates to the technical field of oilfield plugging agents, and relates to a plugging agent for inert materials while drilling and a preparation method and application method thereof. Background technique [0002] Downhole leakage is a phenomenon in which working fluids such as drilling fluid, cement slurry, and workover fluid in the wellbore enter underground high-permeability zones, cave formations, and natural or induced formation fractures during oil and gas well operations. The harm of downhole leakage: the decrease of liquid column pressure causes blowout; causes downhole sticking; aggravates reservoir damage and affects cementing quality; prolongs drilling cycle, increases costs, and in severe cases, oil wells are scrapped. Taking 2003 as an example, the global cost of leak prevention and plugging in drilling was as high as US$800 million, not including the cost of other downhole accidents caused by leakage. As some old oil and ga...
