According to the regulated requirements of high pressure water injection in oilfields, in combination with practical operation rules of field water injection, a technique is summarized by mind science Co.Ltd. For automatically adjusting the switch action of valves, the technique can rapidly trace "allocation of water injection" of flow rate without inducing the damaging injection pipeline by quick action of switch.
On the basis of development of GPRS data transfer module software, different GPRS DTU communication techniques on the market are used by Mind Science. One of the characteristics is that a "heart beating package" is not established in DTU to keep the contact with data center for raising the efficiency of data transmission and saving the fee of communication, second is multi-data centers are allowed to access DTU at the same time, a mode of multi-communication data transmission is realized.
A wireless transmission plat form of GPRS network from china Mobile is used in the wireless remote monitoring network system. GPRS, SMS and CSD are used for self development of an advanced wireless data transfer equipment (GPRS DTU) and integrated it into the "ZJK-I Water Injected Well Intelligent Adjusting Valve" of to build an automatically equipment of high pressure water injection in oilfields. For its data wireless transmission in the oilfields and remotely setting the operation parameters of the intelligent adjusting valve.
