Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
157 words
In an apparatus for measuring the yield of oil wells, particularly where such yield may be irregular, which includes (a) a two-phase separator for receiving oil-gas mixture recovered from the well, (b) means for measuring the yield of the separated oil and gas flows, (c) and a mixer for re-combining the oil and gas flows after measurement, the improvement characterized by, (d) said apparatus including a combined pressure regulator and liquid level control, (e) said combined control including (i) a chamber communicating with the separated oil and gas fluids in said separator, (ii) a float member within said chamber and movable up and down therein as a function of the level of the separated oil, (iii) upper and lower pressure compensated slide valves in said chamber connec ted to said float and movable vertically therewith to progressively open one slide valve while progressively closing the other, and (f) fluid conduits connecting said slide valves with said mixer.
Claim 2
Dependent Claim
157 words
In an apparatus for measuring the yield of oil wells, particularly where such yield may be irregular, which includes (a) a two-phase separator for receiving oil-gas mixture recovered from the well, (b) means for measuring the yield of the separated oil and gas flows, (c) and a mixer for re-combining the oil and gas flows after measurement, the improvement characterized by, (d) said apparatus including a combined pressure regulator and liquid level control, (e) said combined control including (i) a chamber communicating with the separated oil and gas fluids in said separator, (ii) a float member within said chamber and movable up and down therein as a function of the level of the separated oil, (iii) upper and lower pressure compensated slide valves in said chamber connec ted to said float and movable vertically therewith to progressively open one slide valve while progressively closing the other, and (f) fluid conduits connecting said slide valves with said mixer.
Claim 3
Dependent Claim
36 words
An apparatus according to claim 1, further characterized by (a) microprocessor means associated with said yield measuring means, and operative to interrupt the flow of said well for predetermined periods as a function yield conditions measured.
Claim 4
Dependent Claim
25 words
An apparatus according to claim 1, further characterized by (a) said chamber, said float, and said pressure compensated slide valves being located within said separator.
Claim 5
Dependent Claim
25 words
An apparatus according to claim 1, further characterized by (a) said chamber, said float, and said pressure compensated slide valves being external of said separator.
Claim 6
Dependent Claim
26 words
An apparatus according to claim 1, further characterized by (a) means associated with the flow conduit for oil, for measuring the water content of the oil.
Claim 7
Dependent Claim
32 words
An apparatus according to claim 1, further characterized by (a) said float member and said upper and lower pressure compensated slide valves being vertically aligned and rigidly connected for movement in unison.
Claim 8
Dependent Claim
38 words
An apparatus according to claim 1, further characterized by (a) check valves connected in said fluid conduits, between said slide valves and said mixer, to prevent return flow of fluids during interruptions in fluid flow from said well.
