By analyzing the interference rule and numerical simulation, disturbing law of cross flow of multiple well is discussed and he practical use of three phase separator in production system is explained combining field examples.

In order to solve the problems including great loss in oilgas collection transport systems and poorly separative results between oil and gas, a high effective three phase separator was used.

According to the operating principle of a three phase separator for crude oil mixed with water and natural gas, the dynamic mathematical model of it is established.

Trials of a new-type high-efficiency three-phase separator;

In order to solve disadvantages of conventional mechanical measurement methods used in three-phase separator for well testing,a new automatic measurement system was designed and developed.

On the other hand,the design of UASB system must consider the separation of UASB system、three-phase separator、influent distribution system and culture of granular sludge.

A new 3-phase separator is made with this material.

3-phase separator, on the basis of " 4 in one" and structure-improved,can be used in oilfield production,simplifies process flow greatly and combining with optimizing demulsifying agents makes crude desalinization-dewater can be done under lower temperature.

Study on the treatment of low-strength industrial wastewater by new gas-liquid-sludge separator;

Combined with the pilot-scale experimental provision,the authors designed a new gas-liquid-sludge separator which is simple and reasonable in structure.
