Abstract
The invention discloses a microbial powder for removing and inhibiting wax and an application method thereof. The microbial powder is prepared from 15-30% of microbial fermentation powder, 30-40% of wheat middling, 5-10% of inorganic salt, 10-20% of water and 5-10% of organic silica gel. The application method comprises the following steps: (1) lifting an oil suction rod or oil string; (2) uniformly spreading the microbial powder on the outer wall of the oil suction pipe or the inner wall of the oil pipe; (3) taking off the oil suction rod or oil string; and (4) carrying out regular production in the oil well, wherein the load and current of the oil well are detected in the first day of regular production, and detected regularly afterwards. The invention has the advantages of simple construction and low cost, can effectively prolong the oil well hot washing period, reduces the environmental pollution, and thus, can be widely used in oil production.
Description
Technical field
The present invention relates to the clear anti-wax technique that a kind of oil well is used, particularly a kind of clear wax control micro organism powder and using method thereof.
Background technology
Because the reduction of crude oil temperature and pressure in the pit shaft uphill process, and the waxy component in the crude oil is separated out easily in the oil well production process.Thereby on sucker rod and tube inner wall build up, finally cause oil well rod and tube partial-wear, heat to wash increased frequency, well inspection increased frequency, even problems such as serious appearance rod tube disconnectedly takes off, holddown.Have a strong impact on oil well yield, increased energy consumption, brought many influences to production.
In the prior art, patent is called " a kind of microorganism powder preparation for oil production and using method thereof ", the patent No. for " ZL200710043666.5 " though patent more the microbial strains that bacterium liquid design aspect comprises, but exist used activator price higher, and embodiment also is to inject the oil jacket annular space behind the microbial powder dilution agent, the micro organism powder of dilution is drawn out of easily, thereby has influenced clear wax control result and the cycle of micro organism powder.
